It's a Mystery

Wren Sterling knows she's super smart and a good friend, but no matter how hard she tries, she can't shake her reputation as a troublemaker. Her brain just doesn't work like the brains of the other kids at Ada Lovelace Charter School. They all seem to know what's going on. She's just trying to get through the day. It feels like the only people who believe in her are her three best friends in the Renegade Girls Tinkering Club.

When the Renegades start a business inventing and selling spy gadgets, it looks like she's finally done something right. But then they're accused of a school crime! Can they use their own spy gadgets and ingenuity to clear their names? If they can find the real culprit, Wren might just discover she has a bright future after all.

The Babysitter's Club meets MacGyver in this charming story about friendship, middle school, and the Engineering Design Process. All the fun, all the engineering-based life lessons, and a lot fewer babies. THE RENEGADE SPY PROJECT is a perfect next step for kids who loved Rosie Revere, Engineer, the Questioneers, and are now enjoying the Girls Who Code books, and are ready to level up.

Build DIY SPY GADGETS along with the Renegades in this interactive adventure encouraging the STEM in all of us.
